Description

Technical Field

[0001] This application belongs to the technical field of belt conveyors, specifically relating to a gas cleaner for belt conveyors. Background Technology

[0002] A belt conveyor is a friction-driven machine that transports materials continuously. It mainly consists of a frame, conveyor belt, idlers, rollers, tensioning devices, and a transmission system. It can transport materials along a defined conveyor line from the initial feeding point to the final unloading point, creating a material transport flow. It can transport both bulk materials and packaged goods. Besides pure material transport, it can also be integrated with the technological requirements of various industrial production processes to form rhythmic assembly line transport operations.

[0003] Belt conveyors have advantages such as large conveying capacity, simple structure, convenient maintenance, and standardized components. They are widely used in mining, metallurgy, coal and other industries to convey loose materials or packaged goods. Depending on the conveying process requirements, they can be used as a single unit or multiple units can be combined or combined with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of different layout types of work lines.

[0004] When applied in the coal industry, coal chemical conveyor belt chutes are fully sealed and equipped with dust removal systems to meet environmental protection requirements. However, there is still a significant amount of dust in the conveyor belt corridor. The reason for this dust is that existing sweepers cannot completely remove the fine particles adhering to the belt after unloading. As the belt continues to rotate, these fine particles fall off and float in the air when passing the lower idler rollers, causing a poor environment and making sanitation difficult. Since existing sweepers on the market cannot achieve the desired cleaning effect, a new belt sweeper has been specially designed to thoroughly clean fine particles to meet environmental protection requirements, aiming to solve the on-site dust and sanitation problems. Utility Model Content

[0005] This application provides a gas cleaner for belt conveyors to solve the aforementioned technical problem of fine particles falling and floating in the air, causing a poor environment and making cleaning difficult.

[0006] The technical solution adopted in this application is as follows:

[0007] A gas cleaner for a belt conveyor includes a support assembly. The support assembly includes a steel pipe structure extending below the drive roller of the belt conveyor. Several jetting components are fixedly fixed to the steel pipe structure at intervals. The jetting components are fixed to the steel pipe structure by threaded connectors. One end of the steel pipe structure is connected to a pneumatic control assembly through a sealed connection. The pneumatic control assembly includes a ball valve and a pneumatic solenoid directional valve arranged in series. The inlet end of the pneumatic solenoid directional valve is sealed to the outlet end of the ball valve, and the outlet end is connected to the steel pipe structure. The inlet end of the ball valve is sealed to an external air source pipeline. The pneumatic solenoid directional valve is connected to the drive motor of the drive roller of the belt conveyor through an electrical signal cable. The interface end of the signal cable is embedded in the control box of the drive motor to form an opening and closing interlocking mechanism. The support assembly also includes a fixed frame and an adjusting frame. The fixed frame is fixed to the belt conveyor frame by a detachable connector. One end of the adjusting frame is rigidly connected to the steel pipe structure, and the other end is movably connected to the fixed frame through a hinge shaft. A locking mechanism is provided at the hinge shaft to adjust the tilt angle between the steel pipe structure and the belt surface.

[0008] Optionally, the steel pipe structure is a multi-section seamless steel pipe, with adjacent pipe sections connected by a detachable sealing joint, and each pipe section has an annular groove on its surface, with the blowing assembly embedded in the groove and fixed by a lock nut.

[0009] Optionally, the fixed frame is provided with a guide groove, and a mounting seat is provided at the end of the hinge shaft opposite to the adjusting frame, with the mounting seat slidingly engaging with the guide groove.

[0010] Optionally, the locking mechanism is a locking pin with a hinge shaft, and the fixing frame has a locking hole corresponding to the position of the locking pin.

[0011] Optionally, a buffer pipe section is provided between the ball valve and the pneumatic solenoid directional valve of the pneumatic control assembly, with both ends of the buffer pipe section being sealed to the outlet end of the ball valve and the inlet end of the pneumatic solenoid directional valve, respectively.

[0012] Optionally, the spray assembly is a fan-shaped nozzle, which is vertically fixed to the surface of the steel pipe structure by a threaded connector. The spray port axis of the fan-shaped nozzle forms an acute angle with the extension direction of the steel pipe structure, and the orientation of the spray port is opposite to the direction of belt operation.

[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0014] 1. By connecting the ball valve in series with the pneumatic solenoid directional valve and forming an opening and closing interlock with the drive motor of the active drum, the gas cleaning is only activated when the belt is running, effectively avoiding accidental activation and waste of air source; the blowing assembly is fixed at intervals along the steel pipe structure, and the blowing angle is opposite to the direction of belt running, making the cleaning more thorough;

[0015] 2. The detachable pipe section design simplifies on-site debugging and replacement work, and the annular groove with the locking nut improves the fit between the nozzle and the pipe body, enhancing structural reliability. Attached Figure Description

[0022] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0024] A gas cleaner for a belt conveyor includes a support assembly 1. The support assembly 1 includes a steel pipe structure 11 extending below the drive roller of the belt conveyor. A plurality of jetting components are fixedly fixed to the steel pipe structure 11 at intervals. The jetting components are fixed to the steel pipe structure 11 by threaded connections. One end of the steel pipe structure 11 is connected to a gas path control assembly 3 via a sealed connection. The gas path control assembly 3 includes a ball valve 31 and a pneumatic solenoid directional valve 32 arranged in series. The inlet end of the pneumatic solenoid directional valve 32 is sealed to the outlet end of the ball valve 31, and the outlet end is connected to the steel pipe structure 11. The pneumatic electromagnetic reversing valve 32 is sealed to the external air supply pipeline and connected to the drive motor 9 of the belt conveyor drive roller via an electrical signal cable. The interface end of the signal cable is embedded in the control box of the drive motor 9 to form an opening and closing interlocking mechanism. The support component 1 also includes a fixed frame 12 and an adjusting frame 13. The fixed frame 12 is fixed to the belt conveyor frame 10 via a detachable connector. One end of the adjusting frame 13 is rigidly connected to the steel pipe structure 11, and the other end is movably connected to the fixed frame 12 via a hinge shaft 4. A locking mechanism 5 is provided at the hinge shaft 4 to adjust the tilt angle between the steel pipe structure 11 and the belt surface.

[0025] Reference Figures 1 to 4 When the drive drum of the belt conveyor starts and drives the conveyor belt, an external air source supplies air to the air circuit control component 3. The air source first enters the ball valve 31, and after the air flow is controlled by the ball valve 31, it is guided by the pneumatic solenoid directional valve 32 to the interior of the multi-section steel pipe structure 11 extending below the drive drum. Several spraying components on the steel pipe structure 11 are evenly distributed with the help of threaded connectors, and high-pressure airflow is sprayed from each spraying component onto the belt surface.

[0026] Furthermore, the steel pipe structure 11 is a multi-segment seamless steel pipe, with adjacent pipe segments connected by a detachable sealing joint 111, and each pipe segment has an annular groove 112 on its surface, with the blowing assembly embedded in the groove and fixed by a locking nut.

[0027] Reference Figure 2 , Figure 4 The steel pipe structure 11 adopts multi-section seamless pipe fittings, which are connected by detachable sealing joints 111 for easy installation and maintenance. Each pipe section has an annular groove 112 on its surface. The threaded connector of the spray assembly is embedded in the groove and locked with a lock nut to effectively prevent the nozzle from loosening under the action of high-pressure airflow.

[0028] Furthermore, the fixed frame 12 is provided with a guide groove 6, and the hinge shaft 4 is provided with a mounting seat 7 at one end away from the adjusting frame 13. The mounting seat 7 is slidably engaged with the guide groove 6.

[0029] Reference Figure 4The fixed frame 12 is mounted on the side of the frame 10 via a detachable connector. One end of the hinge shaft 4 is slidably engaged with the guide groove 6 of the fixed frame 12 via the mounting base 7, and the other end is connected to the adjusting frame 13 and rigidly fixed to the steel pipe structure 11. The adjusting frame 13 can move around the hinge shaft 4 and, in conjunction with the locking mechanism 5, adjust the tilt angle of the jet blowing assembly relative to the belt surface.

[0030] Furthermore, the locking mechanism 5 is a locking pin 51 through which the hinge shaft 4 passes, and the fixing bracket 12 has a locking hole 52 corresponding to the position of the locking pin 51.

[0031] Reference Figure 3 The locking mechanism 5 is a locking pin 51 that passes through the hinge shaft 4. After the locking pin 51 is inserted into the locking hole 52 on the side wall of the hinge shaft 4, the position of the adjusting frame 13 remains unchanged by fastening, thus ensuring the stability of the spray angle.

[0032] Furthermore, a buffer section 8 is provided between the ball valve 31 and the pneumatic solenoid directional valve 32 of the pneumatic control component 3. The two ends of the buffer section 8 are respectively sealed and connected to the outlet end of the ball valve 31 and the inlet end of the pneumatic solenoid directional valve 32.

[0033] Furthermore, the spraying assembly is a fan-shaped nozzle 2, which is vertically fixed to the surface of the steel pipe structure 11 by a threaded connector. The spray port axis of the fan-shaped nozzle 2 forms an acute angle with the extension direction of the steel pipe structure 11, and the direction of the spray port is opposite to the direction of belt operation.

[0034] Reference Figure 2 The blowing assembly uses a fan-shaped nozzle 2, whose nozzle axis forms an acute angle with the extension direction of the steel pipe structure 11 and faces the opposite direction to the belt running direction. The airflow spreads out in a fan shape after passing through the nozzle, resulting in a larger cleaning area and better cleaning effect.

[0035] Working principle:

[0036] During operation, external air enters the air control component 3 through ball valve 31. Ball valve 31 is connected in series with pneumatic solenoid directional valve 32 and linked to the signal line of drive motor 9. The solenoid valve only opens when the belt is running. The airflow enters the steel pipe structure 11 through buffer pipe section 8, and then is sprayed onto the belt surface through each spraying component to blow away the attached material. Support component 1 is connected to frame 10 through fixed frame 12, and the spraying angle can be flexibly adjusted through adjusting frame 13 and locking mechanism 5. The multi-section detachable pipe section and wear-resistant sheath design ensure the ease of maintenance and durability of this device.
